Fig. 5: Impaired survival of 4xSNCA mDA neurons exposed to fibrils.

A Schematic view of the protocol to intoxicate cortical and DA neuronal cultures with P91 αSyn fibrils. B Live/dead fluorescence staining and quantification of iPSC-derived cortical neurons with or without exposure to P91 fibrils. C Live/dead fluorescence staining in iPSC-derived DA neurons with or without exposure to P91 fibrils and relative quantification (for each group n = 50 fields, automatic counts). Values are mean ± SEM of n = 3 biologically independent experiments. **p < 0.01, ***p < 0.001. Statistical analysis is performed using two-way ANOVA followed by the Bonferroni post-test. Scale bars, 100 µm.
